Delrin™ Acetal
Delrin™ a Dupont acetal resin, is a highly
versatile engineering plastic with metal-like properties. It offers
an excellent balance of desirable properties that bridge the gap
between metals and ordinary plastics. The chemical composition and
highly crystalline structure of Delrin™ acetal homopolymers
offer a unique combination of physical properties not available
with metals or most other plastics. Because of these properties,
this material creates a wear surface, which is excellent for bearings,
bushings and cams.
Stanyl™ Nylon 46
Stanyl™ TW341 is a nylon 46 resin used when
a higher use temperature is required than nylon 66 can withstand
for prolonged periods of time. Stanyl™ exhibits a melting
temperature of 295 °C (560 °F) as well as higher crystalline
structure compared to PA66. This feature give Stanyl™ a technical
edge over other engineering plastics regard to heat resistance,
mechanical properties at elevated temperatures, wear and friction
behavior.
Zytel™ Nylon 66
This material possesses an outstanding balance of
properties, combining strength, moderate stiffness, high service
temperature and a high level of toughness. Because of its low coefficient
of friction, resistance to repeated impact, and resistance to abrasion,
it makes an excellent material for bushings, bearings and thrust
washers
Minlon™ Mineral Reinforced Nylon
We use a toughened mineral reinforced nylon 66,
which gives it superior impact strength as measured by both the
Izod and Gardner (falling dart) impact tests. Adding our proprietary
internal lubrication to this toughened resin provides the characteristics
necessary for an extended wear bushing or spanner.
